        摘要：The effect of fine grain casting process on the microstructure and mechanical properties of K418B superalloy has been investigated. Experimental result has shown that the improvement in the distributed morphology and the decrease in size of primary carbide （MC） and γ′ phase for the alloy have been obtained through the fine grain casting process. The low cycle fatigue life of the alloy with fine grain casting at 650 ℃ is three times more than that with convetional casting process.

        摘要：The vacuum refining technology and its effect on structure and properties of ZL101 alloy have been studied. Experimental results show that the porosity of the alloy is decreased by 4 grades due to high vaccum degassing efficiency. In addition, the compactness and mechanical property are raised and grain is refined for ZL101 alloy.

        摘要：Based on the failure analysis of heat resistant steel casting used in heat treatment furnace, the factors, such as chemical composition, solution treatment, modification and gravity die casting were studied. The mechanical properties in room and high temperature, thermal fatigue in high temperature were shown, structure analysis by optic and electronic microscope was examined. Data obtained will be applied to production guide for steel casting and a foundation will be laid in substituting casting for the forging.

        摘要：The internal microstructure of centrifuge casting cylinder sleeve has been improved by using the new internal chilling method. It is revealed that inner structure is fined, mesh diameters of hard phases are heightened from grade 3 to grade 1 or 2, and the length of flake graphite is also heightened from grade 4 to grade 6. In addition, central inclusion layer can be eliminated by using this method.

        摘要：The phenomena of Al and Al alloy grain refinement by Ti and B were introduced. Several famous theories, such as “Peritectic Reaction”, “Crystal Multiplication”, “Retarcl of α（Al） Crystal Growth”, and a new theory called “Super nucleation” were discussed briefly. Up to now, however, none theory could completely explain all of the phenomenona of grain refinement.

        摘要：The precent progress for Al alloy casting is reviewed. It is pointed out that the mold and core making technology will be developed rapidly in order to meet the need of increasing Al castings in automobile industry. There is a main tendency for Al castings to develop binders for mold and core, improve collapsibility of mold （or core） sand as well as prevent from environment pollution.

        摘要：Based upon a detailed comparable analysis on the actual production status, historical background of application and technological analysis of two different typical casting processes. It is firmly proved that the gravity diecasting process represents the worldwide significant advantage in comparison with low pressure diecasting process on the industrialized casting production of aluminium cylinder heads, which is regarded as one of the most important and complicated component especially for the multiple valve engines widely used today in the modern automotive industry.
